TALKING-MACHINE,REPEATER AND STOP.

Application filed December 23, 1921. Serial No. 524,389.

To all whom it may concern:

Be it known that I, EsKIL H. J osnrHsoN,

a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Talking-Machine Repeaters and Stops, of which the following is a specification.

This invention relates to repeating devices for phonographs and the like and the primary object of the invention is the construction of a novel and an improved device capable of being used in connection with various types of phonographs wherein the selection may be'played and repeated without stopping the turn table.

Another object of the invention is the provision of a repeating device for phonographs and the like cooperatively arranged with the tone arm, including means adapted to be engaged by the outer periphery of the turn table, whereby the said tone arm is moved to its initial playing position. I

Another important object of the invention is the provision of a repeating attachment for phonographs which may be set to play continuously or a predetermined number of times, including an adjusting mechanism so that the device 1s capable of use with various size records as well as permitting repetition of certain portions of a record as desired.

A further object of the invention resides in the construction of a repeating attachment for phonographs, including a novel and improved gear mechanism operable by a friction wheel from the turn table permitting the tone arm to be moved to its initial playing position automatically.

A still further objectof the invention is to provide a repeating attachment of the above character which will be durable and efiicient in use, onethat will be simple and easy to manufacture and one'which can be placed uponthe market and incorporated with a phonograph at a reasonable cost.

With these and other objects in View the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which drawings,

Figure 1 is a plan view showlng the device in its relation with a tone arm of a phonograph,

Figure 2 is a View taken on the line 2-2 of Figure 1,

. Figure 3 is a view-taken on the line 8.3 of Figure 2, showing the friction wheel and trip mechanism, I

Figur 4:.is a further View taken on the line 41 of Figure 2.

I Referring to the drawings in detail, wherein similar reference characters designate corresponding 7 parts throughout the several views 5 designates the turn table and 6 the tone arm having the usual reproducer 7 attached thereto, the same being common to various types of phonographs' rockable receives'the reproducer engaging L-shaped rod 12 which embodies the short leg 87 and the long leg 13, the outer end of which engages the'bracket 14 on the g 1,505,261 PATENT 1 OFFICE.

reproducer 7. Attached to the casing 10 and adjacent the top thereof, I have provided an adjustable bracket 15 formed with a. collar 16 adjustableby means of a screw 17 to'various positions, so that different size records may be'played or such portions of a record, as desired may be repeated during the continuous operation of the turn table. The bracket 15 is provided with'a vertical arm 18' which engages the long leg of the L-shaped rod 12 when-the rod is in its initial playing position. v

It will be observedthat the leg 13 of the L-shaped rod 12 is inclined downwardly with respect to the horizontal when the same is in its normal. or initial position and that the short leg 37 is inclined with respect to the vertical fora purpose which will presently appear.

Pivotally mounted within the housing 8 I have provided a gearing-mechanism for,

by the entire gea-r mechanism and frame may be rocked on a pivot post 24 which is rotatably carried by a bracket 25 attached to the casing 8.

A friction wheel 26 is disposed between the plates 19 and and is rotatable with a post 27 which is mounted in suitable bearings carried by the plates. The friction wheel 26 extends through a slot 28 in the Thus it. can be seen that while the gear frame is pivotally mounted on the post 24:,

the post isadapted to rotate and consequently operates the cam counter clockwise which is connected to the upper end thereof. This cam '35 overlies the top plate 19 and is provided with a pocket 36 therein for receiving the lower end of the short leg 37 of the L-shaped rod 12, so that when the gear mechanism is put into operation by the friction wheel engaging the turn table the vcam will rotate moving the lower end of the short leg 37 about the pivot post 2% rocking theL-shaped rod on the curved top ll of the casing 10, which wiil'lift the leg v 13 and move the same laterally with the reproducer back to its initial playing position.

It is to be understood that when the reproducer reaches its initial playing position that the continued rotation of the cam 35 will further rock the -Lshaped rod and gradually lower the leg 13 until the needle of the r-eproducer engages the record at the point where it is desired to be repeated.

Adjacent to the hollow casing 10 there is provided an adjustable stop member 450 embodying a vertical leg and a substantially horizontally disposed leg. The vertical leg is .rotatably carried by the top wall "9 of the housing 8 and by a bracket 41 secured v to the casing 10. The substantially horizontally disposed leg of the stop member 40 is provided with an upwardly bent end 42 for engaging the leg 13 of the L-shaped rod 12 so as to form a stop for the same, as set forth above. The lower-end of the vertically disposed leg of the stop 40 carries a pair of friction washers 43 between which the curved arm 44; is grasped, the arm lying adyacent. to the inner wall of the housing '8 (see Figure The opposite end 45 of the curved arm ii is adapted to engage the outer end 46 of the curved lock and trip arm 47 which is pivotally mounted as at 4:8 to

the housing 8. The opposite end oft-he arm 47 is provided with a depending foot 49, which engages a notch 50 in the outer end ofone arm 50 of a T-shaped bar 51. The T-shaped bar 51 is pivotally mounted on the plate 19 by means of a pin 53 and the leg or stem thereof isconnected with the trip and lock :arm 47 a coil spring 52. In other words one end of the spring 52 is connected to the arm 47, thus being indirectly connected to the housing 8 andthe opposite end of the spring is attached to the T-shaped' bar 51 and consequently indirectly attached to the gear frame. The'T-shap'ed bar 51 is provided with an arm "54 extending oppositely from the arm 50" :and this arm engages the cam surface of the cam plate 35. Now it is to be noted at this point that when the foot 49 engages the notchx50 on the arms '50 of the T-sha-ped bar that movement of the arm 50 and 'T-shaped bar is limited causing a pivot point at 49 and 50 and the spring 52 acting on the" leg or stem of the bar will cause force to be applied to the gear frame at the pivot point 53 of the T-shaped bar 51. thus turning '51 about 4'9 and 50 which will tend to rock the frame on the post 24 and thus normally hold the frame in and the friction wheel 26 out of engagement with the turntable.

In order to bring about the repeating of the selection and the stopping of the turn table when the record or selection has been troller disk 55 is provided which is secured to the'lo-wer end of a pivot pin .or post 56 rotatably supported by the top wall "9 of "the housing 8. This disk is adjusted by the means of a finger piece 57 which is secured to the pin or post 56 and is adapted to operate over the upper surface of the said well 9. A plurality of teeth '56 is formed on one portion of the periphery of the disk and the disk may be set'accord-in-g to yarious designations on the top 9, so'thatthe record may be played continuously or once, twice, (three or four times which of course depends upon the number of teeth that may be provided.

A bell crank shaped brake arm 57 is provided and pivoted at its angle to the lowe surface of the top plate 9 of the housing '8 and one endof the brake arm is provided with a brake shoe 59 which is adapted tobe normally moved into engagement with the periphery of the turn table of the phonograph for bringing about the stopping thereof by a leaf spring 57% which is also carried by the housing 8.- The opposite end of the brake arm .57 is provided with a foot for engaging the curved portion of the periphery of the controller :disk 55,. Now it is to be noted that the controller disk :55 at the periphery thereof is provided with a notch the brake arm rides into the notch that the brake arm is free to rock on its pivot under influence of the spring 57 and that the brake shoe 59 will be brought into frictional contact with the turn table.

lVhen the controller disk is rotated in a counter clockwise direction so as'to position all of the teeth 56 out of the path of the leg 37 of the L-shaped rod 12, it will be recognized that the device will be set to play continuously and that the foot of the brake arm will be in engagement with the curved edge of the disk and be held out of engagement with the turn table. lVhen the disk is set to repeat the record one or more times the disk is positioned so that one or more of the teeth 56 will be successively engaged by the leg 37 of the L-shaped rod 12 according to the number of times that the record is to be played. It is to be understood of course that the teeth of the controller disk 55 are adapted to be engaged by the leg 37 of the rod 12 and that when the leg 37 is rotated about the pivot 24 by the cam 35, the leg will engage between the teeth 56 and move the disk 55 one tooth at a time upon each rotation of the cam 35. Now it can be seen that when the leg 37 moves the last tooth 56 over, the foot on the brake arm 57 will ride oil of the curved surface of the disk 55 into the notch of the disk thereby allowing the brake arm to be moved to its opera tive braking position.

A coil spring 60 is provided for aiding in the return of the tone arm to its normal position and this spring will function so as to normally tend to rotate the L-shaped rod 12 toward the arm 18 of the stop 15. As shown this spring 60 is coiled about the leg 37 of the L-shaped rod 12 and attached at its upper end to the rod and at its upper end to a stud 61 carried by the extension 62 of the top wall 9 of the housing 8. This extension extends inwardly toward the center of the casing 10.

It is to be noted however that when the" switch not shown to close a circuit connected up with the operating mechanism of the phonograph.

In operation of the improved repeating attachment the stops 40 and 15 are adjusted to the size of the selection being played after which the needle is placed in the outer groove of the record and the tone arm mov ing inwardly will rotate the L-shaped rod 12 in the pocket 36 until the end of the selection is played at which time the leg 13 of the L-shaped rod 12 will engage the stop and trip 40 which will rock the same in the trip and stop 40 will rock the arcuate arm 44 which in turn will rock the trip and catch arm 47 moving the foot 49 thereof from out of engagement with the arm 50 of the T-shaped bar 51. This will now permit the gear frame to be moved outwardly of the housing 8 toward the turn table under the influence of the spring 52 and the friction wheel 26 will be held in contact with the turn table by the said spring.

The rotation of the friction wheel 26 operates the meshed gears 29 and 30 which in turn operates the gear 32 on the vertical shaft 24 and consequently rotates the cam 35 mounted on the upper end of the shaft 24. The. rotation of the cam 35 which carries the lower end of the leg 37 of the reproducer engaging rod 12 consequently effects the movement thereof when rotated. The rotation of the cam 35 rocks the L-shaped rod 12 so as to cause the raising of the leg 13 and the canted position of the leg 13 and the stop spring 60 will move the arm back against the stop 15 to its initial position, The continued rotation of thecam 35 will again change the angle of the reproducer arm 12 and permit the lowering of the reproducer until the needle engages in the first sound groove. As soon as the cam 35 is operated through the gears, the same will. at once act on the curved end of the arm 54 of the T-shaped bar 51 rocking the same 011 .its pivot 53 and moving the arm 50 thereof'under the foot 49 of the trip arm 47 consequently again latching and holding the T-shaped bar. lVhen the high point of the cam 35 engages the curved end of the arm 54 of the T-shaped'bar 51 the reproducer will be in its lowered position and when the curved end of the arm 54 rides ofi of the high point of the cam a pivot will be produced at the foot 49 and notch 50 and causing force to be applied to the gear frame.

or casing at53 thereby turning the T-shaped bar 51 at the point 49 and 50 thus rocking I the gear frame on the pivot 24 moving the friction wheel 26 from out of engagement with the turn table. The turn table will of course again start rotating and the rod 12 will be moved inwardly with the reproducer starting the operation of the repeating at tachment over again.

Assuming that the regulating or controllerdisk .55 is set to play the selection once, and the end of the leg 37 of the L- shaped rod 12 engages the innermost tooth 56 causing the rotation of the disk 55 one tooth, this foot of the-brake arm to ride into the notch 60. The brake arm 5'? will be released and the turn table will be brought to a stop. 'The rotation of the cam 35 will of course also engage the curved end of the arm 54,- of the T-shaped rod 51, so that the catch will be moved to its initial locking position as heretobefore described.

'By moving the point or indicator 57 to its various designated positions on the casing the disk dish 55 can be set, as the same cooperates therewith and the selection may be repeated a number of times or if so desired can be played continuously, as heretofore stated.

In the accompanying drawings I have illustrated my invention embodied in one form by way of example and which construction has been found to answer a satisfactory degree the results to be obtained. It would be manifest, however, that other forms or embodimentmay "be adopted and that the construction may be variously changed and modified by the skilled mechanic without departing from the spirit of the invention.
